Photocoupler Systems Using Laser Diode.

Due to recent progress in semiconductor lasers, small-sized optical sources with good coherency characteristics are easily obtainable. Using semiconductor lasers instead of previously employed light-emitting diodes, it is believed that construction of new photocoupler systems is possible. En this paper, using the coherent light, the basic behavior of photocouplers is discussed and parallel and serial photocoupler systems with new functions are proposed. [ABSTRACT FROM AUTHOR]
